To all whom it may concern:

Be it known that I,.DAv1n A. Mnoornr, a citizen of the United States, residing at Salt Lake City, in the countyof Salt Lake and State of Utah, have invented certain new and useful Improvements in a Combined Reconstruction, as hereafter shown and described and specifically pointed out in the claims, and in the drawings illustrative ofthe embodiment of the referred form of the invention, Figure 1 1s a sectional elevation. Fig. 2 is a longitudinal section on the ,line 22 of- Fig. 1 looking inwardly in the direction of the arrow. Fig. 3 is a transverse section on the line 3-3 of Fig. 1. Fi 4 is a diagrammatic view on a reduced scale show-- ing the improved device arran ed in connection with a conventional steam eating lant, including the generator and two of t e radiators.

In Fig. 4 of the drawings is shown a conventional generator having a smoke stack 11, two radiators indicated at 12 with the return pipes 13 leading therefrom, these parts being of usual form.

The improved device is located between the radiators and the generator, at any con- 'venient point, preferably near the generator,

as indicated, and consists in a casing 14, preferably elongated and divided by an intermediate partition. 15 into two com artments 16-17, the com artments 1'6 referably larger than t e compartment 17.

eing

he partition 15 is provided at its lower end 1 witha transverse aperture 18 providing communication'between the two compartments,

- and leading from the casing 14 is a discharge casing and beneath the partition 15, so that water will flow from both compartments into' the discharge. 1

The casing 14 s rovided with a cover 20,

preferably bolted t iereto, as at 21, so that it can be easily removed. The cover 20 is pro- '55 'vided'with a sleeve 22 having a valve seat 23 p pe. 19, preferably arranged centrally of the.

. a similar sleeve 24 is arranged in the cover 20 and communicating with the compartment 17 and having a valve seat 25. A rod 26 extends through the sleeve 22 and terminates in a float 27 preferably Weighted, as indicated at 28. Attached to the upper end of the rod 26 above the cover 20 is a chain 29, leading over suitable guide pulleys 30 and connected to the damper 31 of the generator 10, so that the rising and fallingof' the float 27 will efiect the opening. and closing of the damper 31,- as

hereafter ex lained. The rod 26- is also rovided wit a valve 41, preferably near the 0st 27, and adapted to engage the seat 23 when the rod is elevated to a sufiicient extent as hereafter explained.

Connected to the outer end of the sleeve 24 is an elbow 32 from which an air pipe 33 leads into the smoke stack-11, or other convenient Ipoint.

The seeve 24 is provided wlth a guide spider or similar device 34, through which a rod 35 is slidably disposed 'and extending into the compartment 17, and provided at its lower end With a float 36, and at an intermediate point, preferably near the valve seat 25, with a valve 37 adapted to engage the seat-25 when the rod35 and its float are elevated toa sufficient extent.

A Water gage 38 is connected to the casing 14 and communicating with the compartment 16, and arranged upon the casing 14 'opposite the gage 38 are indicator lines 39,

to denote the air pressure in the casing. Thereturns 13 from the radiators are united into a pipe 40 leading into the compartment 17 near its upper end, as shown. By this I arrangement it will be obvious that when the float 36 in the chamber 17 is under alow pressure, preferably about one ounce, the

valve 37 will close against the seat 25 and shut ed the flow through the elbow 32 and its ipe 33. i

he float 27 in the compartment 16 is designed tomegulate the-ounces of pressure carried in the system, and can be raised and. fastened to any desired point upon the chain 29 to correspond to any required number of ounces of pressure desired, and the damper .will be closed at this predetermined pressure, and the corresponding check draft opened. WVhen the pressure of water in the com partment 16 is suflicient to raise the float 27,, the valve 41,on the rod 26 closes the-opening.

at the top of the compartment 16,. which seals the ent re system, thereby enabling the operator to carry any desired amount of pressure of steam without the. loss of any of the steam.

The artition 15 between the compartments seals the steam connection between the two compartments, and thuspreventing the steam from passing from one compartment 'to the other.

therefrom when the water causes said float to rise to a certain predetermined level, a float in the other-compartment, means for 'connectin said last mentioned float with the damper o the generator, and a valve associated with said last mentioned float and adapted to close the outlet from the said last mentioned compartment when the water causes the float thereof to rise to a certain predetermined level.

2. in a steam heating system, a single re ceiver divided into two compartmentswi'th an outlet from each and a pipe adapted to conduct the water from the receiver to the generator of the system, afloat in each of said compartments, a valve associated with each of said floats and operative to close the .outlets thereof when thewater rises to a certain predetermined level, connecting means between the float of one ofsaid compartments and the damper of said generator, and means for conducting the return water from the radiators to the other'of, said compartments, the return water having an unrestricted passage into the receiver.

3. In a steam heating system, a receiver divided into two compartments with an outlet from each and with a pipe adapted to conduct the. water from the receiver to the generator' of the system, a floatin each of said com artments, a valve arranged. to be operated by one of said floats to close the outlet to one of said compartments whenthe Water rises a relatively short distance, and a valve arranged to be operated by the other of said floats. to close the outlet to the other of said' com artments when the water rises a relative y long distance, connecting means be tween the fioat and one of said compartments and the damper of said generator, and means seasei for conducting the return water fromithe radiators to the other of said compartments,

sage into the receiver.

4:. In a steam heating system, a receiver divided into two compartments with an outlet from each and a pipe adapted to conduct the water from the receiver to the generator of the. system, a float in each of said com- .partments, a valve associated with each of said floats and operative to close the outlets thereof when the Water rises toa certain prethe float of one of said compartments and the dam er of said generator, means for conductot er of said compartments, the return water having unrestricted passage into the receiver a water gage connected to said receiver, and spaced graduations associated with said watel gage.

5. In a steam heating. system, a receiver having a partition ofl from its center dividing it into two compartments with an outlet from'each and with a pipe adapted to conduct the water from the receiver to the generator of the system, means for conducting merits, means for closing the outlet to said return receiving compartment when the water rises a relatively short distance, means for closing the outlet of the other compartment when the water rises a relatively long distance, and connectin means between said last mentioned outlet 0 osing means and the damper of the generator of the'system.

6. In asteam heating system, -a receiver having a partition off from its center dividing from each and a pipe adapted to conduct the water from the receiver to the generator of the system, a float in each of said compartments, a valve associated with each of said floats and operable to close the outlets of the compartments when the water rises to a certain redetermined level, the valve of one float eing s aced a greater distance from its float than t e spaced relation ofthe other valve with its corres' onding float, connecting means between tie float of one of said compartments and the damper of said generator, and means for conducting the return waterfrom the radiators to the other of said compartments.
